geur 10 of the drivel shaft. llhen the gears 55 To all r11/1.0m it 'may eo'ncm'n:

Be' it known that l, Rossem llorr, e citizen ot the United States, and resident olI Detroit, Wayne county, Starte ot h'liehignn, have invented certain new :ind useful lxnrovements in Transmission-Gear for Motoreliieles, of which the following is n specification.

The object of the present'invention is to improve the construction and arrangement f trensniission gearing for motor vehicles and more pertieulerly trnnsinission gein-ing arranged et and 'direetly eonneeted with the rear or driving ttxle. The invention will he described in connection with the iieeoinpnny- 4 ing drawing, in which,

Figure 1 is n suhstantially horizontal seetion through the rear axle sind the easing ot the transmission gear; Fig. 2 is a vertical ysection on the line 2-2 ot Fig. 1.

Referring to the drawings, 1 indicates e gear ense, 2 the rear axle castings which :ire rigidly connected with the ,gear case, 3 the sections of the rear axle, 4 ,the housing,r of the differential gears and the gear surrounding and connect-ed to the said housing and which drives the sinne. The dill'erentinl gears In :1y be of any aoproved construct-ion, it being understood t mtthey :ire connected to the two axle sections 3 in some suitable nizinner.

The ehenge speed gearing com rises gears 6, 7, sind 8, fixed on e. counter-s aft S), end gears 10 and 11 arranged to slide on and turn with e drive shalt 12, the gear 11 being adapted to rfooperfite with the gear 6 sind the gear 10 adapted to cooperate with the gear 7. I` he gears 10 and 11 :ire preferably connected together hy a eonnnon huh or sleeve and are adapted to he shil'ied lmigitudin:i115v on the shaft 12 by e. rod 13 and e yoke 14.

The gear which turns the (,li'fleren'tinl housing; is driven by n beveled gen1' 1.3 Carried by a short shalt 16 which. is mounted in. e ball bearing 17, the outer rin;r ot' .the ball beeriinT heiner sented in n ring 18 whieh is edjustablDT threaded into the easing 1 and adapted to he held in any desired position hyi threaded ring 1) which serves n lock nut. At its rear end the shaft 16 is carried in a. hall bearing 20 mounted in the easing l find :it its front end it. carries e. eluteh gear 21 which is provided with external teeth in mesh with the gear 8 of the counter-shaft end with interuel teeth adapted to inter-mesh with the 1U or 11 interinesli with one ot the gears ol' the counter-shell, the dill'erentinl is driven hy ineens ol' the ,genre 8 end 21. When however the gear interineshes with the frein' 21,' the dill'erential is driven directly,Y l'roni G0 the drive shalt 12 end the oonliter-slinltruns idle, lhe gez'irs 10 end 21 forming; :i chilli-.h for direct connection.

A thrust hearing; 22 is interposed hetween the pinion and the ring lf), the seid henre5 ing comprising n. ring 23 lixed on the pinion :md n series ol' halls between 'the ring,f 2? end the riinr 1h. The supporting rings 18 und 1l) for 'the nearing; 17 are preferably mounted in r e llenge 24 or the raising, which thing( and 70 hearing 'torni n partition dividing; the change speed geni eoinpnrtnient,from the dill'erentml compartment. of the easing. The slui'lt 1d extends through snid partition end (ferries the gear 21 in one compartment und the geur 75 15 in the other. The drive shzi'lt 12 hns e bearing 25 1n the l orwnrd end ol' the easing 1 and its r'enr or free end is journaled in :i suitable hall hearing 26 in the forward end ol the shaft .16 adjacent to the eluteh geur 21. threaded rings 18 and 19 permit ofV adjusting the shaft 16 lengthwise to some degree to adjust the lnesh ol the beveled gears 5 end l5 accurately.

The easilynr 1 is )rovided with mssnees or 85 e. l r s duets 27 lending from the interior ol' the axle casingsv2 to the lower' part 28 of the easing. The gears in the easing run in oil which oilis carried up from the bottoni 2S to the top 01E the casino and through the Abearings 29 of the dill'erentinl housing into the space between the axle seetions and their ensings. 'lhis oil is prevented from 'prise-ing outward through the seid speee to the wheel hubs by packing materie. 95

3l) which is interposed between the axle sertions end their erisings and held in pince by oups or rings 31, 32 which are pressed into the axle ensings :ind have .flanges engaging. the Axle cesings lrotionnlly. n'niterizil 3() is outside ol the upper ends ot' the duets 27 and vthe oil which circulates through the hearings into the axle ensings returns by seid duets to the lower inert ot' the gear ense. the `axle hearings ond the hearings of the shaft 16 ere likewise lubricated oy oil carried up by the gear 5.

The 8o nrt of it .finds its wav 'lhe peeking 1,00

The oil. is thus circulated through '105 Having described my invention what eluiin and desire to ,secure by' Letters-Patient, is, Y l, I v

1. In transmission gearing for motor ve- `hielos, the combination with the Change speedgoaring, the dlil'erentnrl gearing and a4 casing inclosing said gearings, oi a drive shaft, and u shaft interposed between the drive shaft and the different-inl geering,.e clutch geur on one end of snid interposed sooft cooperating with the change speed gearing, and :i beveled geur upon the opposite end thereof cooperating with the differential gearing, e radial hearing vfor said interposed shalt ndjustehly mounted in the easing, adjustubly mounted in the easing, one of said bearings serving :is a loeli for the other.

2. in transmission gearing iior motor vehicles, the combination of rea-r a-Xle casings, :in intermediate easing, dilferential gearing in said intermediate easing, and peeking ineterinl arranged in seid rear 4axle eesings on opposite sides oi' the dill'erentiul wearing, said ensings having conduits leading :from the interior ol" the axle easings to the lower part of the casing containing the dillerentinl gearing.

3. In Itransmission gearing for motor Veand :i thrust hearing for Suid shaft alsov hieles, Vthe combination With rear axle secpeekingnmterizil arranged vin said easingsv 'surrounding the axle seetions, seid easings haring conduits leading frein the space surrounding ihe axles to the lower part of the easing surrounding the dill'erentiel gearing. Ll. in transmission gearing for motor irehieles, the combination with rear axle seetions und intorinodiete differential gearing, of n easing surrounding seid axle sections and gearing, and supporting the differentiel gearing on bearings therein, and paolo ing materiel in said easing end surrounding the axle sections, said easing having oonduits leading from points contiguous to said` peeking to the lower part of the easing.

In Jtestimony whereof I elc my signature 5 in presence of two Witnesses.
